The current work aimed to optimize the photocatalysis of Basic Red (BR51) in hair dye greywater (HDG) using zinc oxide nanoparticles (ZnO NPs) by response surface methodology (RSM). The independent factors included ZnO NPs dose (10–200 mg), pH (3–9) and BR51 (1–10 ppm). The photocatalysis efficiency...
